Since image initialization was moved after tag parsing, the
palette needs to be specified in the context and then copied
to the allocated image in init_image().
Fixes a regression with TIFF images that have palette data,
trac issue #230, file Test_Flate_8bpp.tif.

Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.

When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.
Fixes occasional one-off effects when enabling slice-MT.
The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

This is consistent with how all other table generation programs are named.
Moreover this ensures that the cos table generation program is correctly
deleted when cleaning the tree.
This collapses the make rules for the trig tables into a pattern
rule. Based on a patch by Diego, modified to avoid using fragile
make constructs and allow future addition of fixed-point sin tables.

Make the iff demuxer send the whole audio chunk to the decoder as a
single packet, move stereo interleaving from the iff demuxer to the
decoder, and introduce an 8svx_raw decoder which performs
stereo interleaving.
This is required for handling stereo data correctly, indeed samples
are stored like:
LLLLLL....RRRRRR
that is all left samples are at the beginning of the chunk, all right
samples at the end, so it is necessary to store and process the whole
buffer in order to decode each frame. Thus the decoder needs all the
audio chunk before it can return interleaved data.
Fix decoding of files 8svx_exp.iff and 8svx_fib.iff, fix trac issue #169.
Iam not sure this is the best way to implement it, but its the simplest
and keeps the code seperate from the application. Keeping ffmpeg.c
simple and not requireing user apps to duplicate this code.
